ncloud_put_object_acl

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description only indicates a mutation action ('Set') but does not disclose whether the ACL is overwritten, if it is idempotent, or what permissions are required. With no annotations, the description carries the full burden and fails to provide sufficient behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single, clear sentence that conveys the essential purpose with no redundant words. Efficient and well-structured.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has no annotations and no output schema, the description should cover return behavior, required permissions, and effect on existing ACLs. It does not, leaving significant gaps for a mutation tool with 3 required parameters.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All parameters have descriptions in the schema (100% coverage), so the description adds no additional meaning. The enum for 'acl' is fully documented in the schema. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Set' and the resource 'access control list (ACL) of an object in Object Storage'. It specifies 'using a canned ACL', which distinguishes this from setting bucket ACLs or custom ACLs. Sibling tools include ncloud_get_object_acl and ncloud_put_bucket_acl, making the purpose distinct.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives like ncloud_put_bucket_acl or how to choose between canned ACL and other methods. No prerequisites or context for usage are provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
